Articular disk

Articular Disk

The Articular Disk is a fibrocartilaginous structure found in various joints of the human body. It is a significant component of the joint anatomy, serving as a shock absorber and facilitating smooth movement between the articulating bones.

Etymology

The term "Articular Disk" is derived from the Latin word "articulus", meaning joint, and the Greek word "diskos", meaning a flat, circular object or plate.

Structure

The Articular Disk is composed of fibrocartilage, a type of cartilage that contains a mixture of white fibrous tissue and cartilaginous tissue. This composition allows the disk to be both tough and flexible, making it ideal for its role in the joint.

Function

The primary function of the Articular Disk is to act as a shock absorber in the joint, reducing the impact of physical stress and strain on the bones. It also aids in the smooth movement of the joint by reducing friction between the articulating surfaces.

Clinical Significance

Damage or degeneration of the Articular Disk can lead to joint disorders such as Temporomandibular joint dysfunction and Disk herniation. These conditions can cause pain, stiffness, and reduced mobility in the affected joint.
